Guitarreando: estudo sobre a utilização de modelagem e tablatura no ensino de violão mediado por tecnologia

We focus on the effectiveness of modeling and tablature as strategies for knowledge sharing in technologically based guitar-training techniques. We adopt experimental procedures with the purpose of subsidizing election, design and development of educational musical environments. Forty-one participants performed musical excerpts furnished through three digital media: video, audio and tablature. Activities featured chords using open strings, melodies with open strings, and melodies using pressed strings that require coordination between the hands. The study proposes the following questions: What digital models – video and audio or tablature – are most effective for initial guitar methods? What sonic materials (chord, melody with pressed strings or melody with open strings) are more suitable? Regarding the number of errors and the execution time, the results indicate that tablature is more effective than audiovisual and sonic models. Concerning musical materials, the results suggest the use of activities using open strings during the initial training phase.
